SI8235BD-D-ISR Description

Short technical summary and product information.

The Si823x family of isolated drivers from Silicon Labs, including the SI8235BD-D-ISR, combines two independent, isolated drivers into a single package. These drivers utilize proprietary silicon isolation technology, providing up to 5 kVRMS withstand voltage per UL1577 and fast 45 ns propagation times. Versions are available with peak output currents of 0.5 A and 4.0 A, operating with a maximum supply voltage of 24 V.

Designed for a wide range of isolated MOSFET/IGBT gate drive applications, the Si823x family offers high integration, low propagation delay, and a small installed size. The TTL level compatible inputs feature >400 mV hysteresis. Driver outputs can be grounded to the same or separate grounds or connected to a positive or negative voltage.

Applications include power delivery systems, motor control systems, isolated dc-dc power supplies, lighting control systems, plasma displays, and solar and industrial inverters. Automotive-grade versions are also available, built using automotive-specific flows for enhanced robustness.

The SI8235BD-D-ISR is supplied in a 16-SOIC wide body package suitable for surface mounting.
